PROTECTION PRODUCTS - MicroClamp
Description
The µClampTM series of TVS arrays are designed to protect
sensitive electronics from damage or latch-up due to ESD.
It is designed to replace multilayer varistors (MLVs) in por-
table applications such as cell phones, notebook comput-
ers, and PDA’s. It features large cross-sectional area junc-
tions for conducting high transient currents. It offers su-
perior electrical characteristics such as lower clamping volt-
age and no device degradation when compared to MLVs.
They offer desirable characteristics for board level protec-
tion including fast response time, low operating and clamp-
ing voltage, and no device degradation.
The µclampTM0501H is in a ultra-small SOD-523 pack-
age ideal for use in portable electronics such as cell
phones, PDA’s, notebook computers, and digital
cameras. It will protect one unidirectional line operat-
ing at 5 volts. It gives the designer the flexibility to
protect one line in applications where arrays are not
practical. Additionally, it may be “sprinkled” around the
board in applications where board space is at a pre-
mium.
This device may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV
contact discharge).
